Systems, devices and methods for receiving an item

ABSTRACT

Systems, devices and methods for receiving an item in a receptacle are disclosed. Features are disclosed for receiving and guiding an item in a receiving space of a receptacle so as to attenuate or remove the impact force of the item on the receptacle. Some embodiments of the disclosure include a bumper having an impact surface which absorbs most or all of the impact force of the item and thereby mitigates or removes the imposition of cyclic impact loads on the receptacle from repeated receipt of items. The bumper may be structurally and/or functionally de-coupled or otherwise physically separated from the receptacle such that an advantageous division of labor is created between absorbing the impact and receiving the item. This disclosure may be useful, for example, in modern industrial operations where a high volume of items are received daily, such as in mail sorting and handling operations.

BACKGROUND Field

This disclosure relates generally to item handling. In particular,systems, devices and methods for repeated receiving of items in areceptacle are disclosed.

Description of the Related Art

In many industrial concerns, efficient handling of large numbers ofitems is crucial. For example, many items must be received, sortedand/or delivered accurately and on time. Some operations involvethousands or millions of items handled daily. Typically, automatedmachines and/or assembly lines are used for the operations involved inhandling the numerous items. Cyclic or repeated use of such machines canresult in damaging wear and tear, such as cyclic stress or structuralfatigue. For example, some automated processes involve sorting itemsinto different physical receptacles. These receptacles may receivethousands of such items daily which impact the receptacles upon beingreceived. Over time, the multiple impacts from receiving such items inthe receptacles cause stresses that continually weaken and mayeventually fracture or break the receptacles. Further, in high volumeprocesses, the items and/or receptacles may be moving with high speed inorder to efficiently process many such items. Higher speeds result inlarger impact forces on the receptacle into which the items arereceived. These larger forces compound the problem of cyclic loading andcan cause further damage to the system.

As another example, mail delivery operations may involve automatedsorting and receiving of thousands of pieces of mail daily. The highfrequency and high volume of mail items being received in sorting binsimpose cyclic stresses on the bins. These stresses may fracture or breakthe bins, thereby requiring repair of costly components. Further, thedowntime in repairing or replacing these components causes furtherfinancial loss and other harms to business operations.

This is merely one example of an industrial concern that relies onsorting and receiving high volume items. Others may include, but are notlimited to, retail concerns with large inventories and high daily sales,high volume component manufacturers such as consumer goods, andimporting concerns with high volume imports needing sorting andreceiving daily.

There is therefore a need for improved systems, devices and methods thatcan handle repeatedly receiving a high volume of items without theaforementioned drawbacks.

The terminology used in the description presented herein isnot intended to be interpreted in any limited or restrictive manner,simply because it is being utilized in conjunction with a detaileddescription of certain specific embodiments of the development.Furthermore, embodiments of the development may include several novelfeatures, no single one of which is solely responsible for its desirableattributes or which is essential to practicing the invention describedherein.

Systems, devices and methods for receiving an item received in areceptacle are disclosed. Features are disclosed for receiving andguiding the item in a receiving space of the receptacle so as toattenuate or remove the impact force of the item with the receptacle.Some embodiments of the disclosure include a bumper having an impactsurface which absorbs the impact force of the item and thereby mitigatesor removes the imposition of loads on the receptacle. The bumper may bephysically de-coupled or otherwise physically separated from thereceptacle such that an advantageous division of labor may be createdbetween absorbing the impact and receiving the item. The receptacle maybe allowed to move at a high speed so that a high volume of items may beprocessed or otherwise handled by the system. This disclosure may beuseful, for example, in modern industrial operations where a high volumeof items are received daily, such as in mail sorting operations.

Turning to FIG. 1A, a perspective view of an embodiment of a system 100for receiving an item 10 (not shown) in one of a plurality ofreceptacles 300 is shown. The system 100 may be used in many differentcontexts. The system 100 is suited for operations with handling of items10. The system 100 is also suited for handling high volumes of items 10.For example, the system 100 may be used in an automated operation wheremany items 10 are handled. An embodiment of the system 100 may be in adelivery item handling operation, such as a postal service. Forinstance, many thousands or millions of pieces of mail may need to besorted and received in receptacles 300. Thus, mail handling is oneapplication where the system 100 may be used. Other applications may useor benefit from the system 100.

As shown in FIG. 1A, the system 100 may include a support structure 150,an injector 200 and a receiving system 250. Portions of the receivingsystem 250 are depicted in FIG. 1B. The system 100 may be located in anitem sorting and handling facility. The support structure 150 may beconstructed from steel beams or other rigid structures that support theinjector 200 and/or the receiving system 250. As shown, the supportstructure 150 is a rigid frame formed from mechanically attached steelbeams and defines various sections. The structure 150 may include afirst section 152, a second section 154 and a third section 156. Thefirst section 152 may include the injector 200 and the receiving system250. The second section 154 may include machinery or devices thatinitially provide the items 10 that will be handled, sorted, etc. by theinjector 200 and received by the receiving system 250. People may alsoinitially provide the items 10, for example by loading the items 10 inthe injector 200. The third section 156 is shown empty but may includeother features of the system 100, such as modules for an infeed line(not shown). The receiving system 250 in the first section 152 may bemounted to the support structure 150. The receiving system 250 may alsobe located on the ground, on a platform or on another secure mountingstructure, for example a concrete slab. The injector 200 may be locatedon, above or otherwise positioned adjacent to the receiving system 250,for example on an upper beam of the structural support 150 mounted abovethe receiving system 250.

The injector 200 may be a machine or apparatus that propels or otherwisemoves the item 10 toward one of a plurality of receptacles 300 of thereceiving system 250. The injector 200 may comprise a container such asa bin or bag, for example, configured to store the items 10 to besorted, handled, and/or otherwise processed. The injector 200 may sendthe item 10 moving through the space between the injector 200 and thereceiving system 250. For example, the injector 200 may propel the item10 through the air. In some embodiments, there is more than one injector200. For example, there may be three (3) injectors 200 under which thereceptacles 300 travel. Some of the receptacles 300 may receive items 10from a first injector 200, other receptacles 300 may receive other items10 from a second injector 200 (not shown), and still other receptacles300 may receive other items 10 from a third injector 200 (not shown). Insome embodiments, there are more or fewer than three (3) injectors 200.

The receiving system 250 may include the plurality of receptacles 300, atrack 360, a plurality of bumpers 400, and a base 440. The track 360 maybe an elongated, structural support, such as a wall, for guiding theplurality of receptacles 300. The track 360 may thus be a metal or otherrigid material that guides the receptacles 300 as they move. The track360 may include a single wall or multiple walls. The receptacles 300 maybe moved by a chain (not shown) running along a groove 362 of the track360 that is connected to and moved by a motor (not shown). A knob 335 onone or both the sides of the receptacles 300 may couple the receptacles300 to the moving chain in the groove 362 of the track 360.

FIG. 1B shows the receptacles 300, the base 440 and the bumpers 400 ofthe receiving system 250 from FIG. 1A. Referring to FIGS. 1A and 1B, thereceptacles 300 may move in the direction 15. The receptacles 300 maymove in this direction 15 over the bumpers 400. In some embodiments, thebumpers 400 may be fixed relative to an inertial frame of reference andthe receptacles 300 may be moving relative to that frame. For example,the receptacles 300 may be translating and the bumpers 400 may bestationary. In some embodiments, the receptacles 300 move with a speedof 0.6 meters per second (m/s). Other suitable speeds may beimplemented.

As the receptacles 300 move over the bumpers 400, the bumpers 400 maypartially occupy a receiving space 350 of the receptacles 300 throughnotches 322 in the lower portions of the receptacles 300. When thebumpers 400 are occupying the space within the receptacles 300, theinjector 200 may inject the item 10 or multiple items 10 into one ormore of the receptacles 300. The receptacles 300 may then receive theitem 10 and the bumper 400 may absorb an impact force from the item 10.Each of the receptacles 300 may receive a different item 10. Thereceptacles 300 may then move away from the bumpers 400 in the direction15 to an unloading site (not shown). At the unloading site, thereceptacles 300 may then empty their respective items 10 for furthersorting, delivery, handling, etc. The receptacles 300 may empty theirrespective items from the bottom of the receptacles 300 by opening abottom portion of the receptacles 300.

In some embodiments, there are multiple receptacles 300. In someembodiments, there are ten, fifty, one hundred, several hundred,thousands or other amounts of receptacles 300. In embodiments with morethan one receptacle 300, the receptacles 300 may be grouped intoreceptacle groups 302. For instance, the receptacles 300 as shown aregrouped into three groups 302 of three receptacles 300 in each group302. Each group 302 of three receptacles 300 may be mechanically coupledtogether by two side panels 330 on either side of the group 302. Otherarrangements and group 302 sizes are possible. In some embodiments,there may be two hundred and fifty three (253) receptacles in the group302. Therefore, the system 100 shown in FIGS. 1A and 1B may include morereceptacles 300 than what is depicted. Further, any of the features andfunctionalities discussed herein with respect to a single receptacle 300may apply to embodiments having multiple receptacles 300, and viceversa.

Each receptacle 300 may include a front side 310, at least one sidepanel 330, and a back side 340 (not shown). The front side 310, two sidepanels 330, and the back side 340 may be coupled together to form apartially closed, single receptacle 300. The top of the receptacle 300may be open in order to receive the item 10 in a receiving space 350 ofthe receptacle 300. The bottom of the receptacle 300 may be closed offby a curvature in a lower portion of the front side 310, as discussed infurther detail herein, for example with respect to FIG. 1D-1F. There maybe multiple receptacles 300 grouped together, with each receptacle 300having a front side 310 and a back side 340. The side panels 330 mayclose off the sides of the receptacles 300. For example, threereceptacles 300 may be grouped together and closed off on the sides witha single side panel 330 on each side of the receptacles 300, asdiscussed in further detail herein, for example with respect to FIG. 1E.In some embodiments, there may be two hundred and fifty three (253)receptacles grouped together.

The front side 310 of the receptacle 300 may provide a front structureof the receptacle 300. The front side 310 of the receptacle 300 extendsalong the width and height along the front side of the receptacle 300.The front side 310 may be a substantially planar and generallyrectangular panel, wall or other generally flat structure. The frontside 310 may have a curvature near the bottom portion of the structure.As is discussed in further detail herein, for example FIGS. 1E-1G, thecurvature of a bottom portion of the front side 310 may guide the item10 toward the bumpers 400 that occupy a space inside the receptacle 300,as the receptacle 300 is moving over the bumpers 400. The front side 310may be formed of any suitable material. For example, the front side 310may be made from a plastic, polymer, metal, other rigid material, orcombinations thereof. The front side 310 may have a thickness (shown inthe cross section view of FIG. 1E). The thickness of the front side 310may be about five (5) millimeters (mm). The thickness of the front side310 may be thicker or thinner than five (5) millimeters (mm).

The back side 340 may be a structural side of the receptacle 300 that islocated generally opposite from the front side 310. The back side 340may extend along the width and height on a rear side of the receptacle300. The back side 340 may extend substantially vertically from thebottom of the receptacle 300 and then turn at an angle toward the top(the vertical and angled portions are shown in the cross section view ofFIG. 1E). The back side 340 may be formed from a metal, plastic or otherrigid structure having a thickness. The thickness of the back side 340may be about five (5) millimeters (mm). The thickness of the back side340 may be thicker or thinner than about five (5) millimeters (mm). Theback side 340 may be formed of the same or similar material or materialsas the front side 310.

The side panels 330 may define one or more sides of the receptacle 300.There may be two side panels 330. The side panels 330 of the receptacle300 couple the front side 310 of one of the receptacles 300 to the backside 340 of the same receptacle 300. Multiple receptacles 300 may beassembled together in a group 302 of receptacles 300 that is closed offon two lateral sides by two side panels 330. In some embodiments,multiple groups 302 of receptacles 300 may be assembled together andclosed off on the sides by only two side panels 330 for the entireassembly of groups. The side panels 330 may be substantially planarpanels, walls or other generally flat structures. They may have acontour or perimeter that complements the sides of the receptacles 300with which they are coupled. For instance, an edge of the side panel 330that couples with the front side 310 may be flat with a curvature nearthe bottom to complement and couple with the front side 310, and an edgeof the side panel 330 that couples with the back side 340 may bevertical from the bottom and then angled to complement and couple withthe contour of the back side 340. The side panels 330 may be formed ofany suitable material. For example, the side panels 330 may be made froma plastic, polymer, metal, other rigid material, or combinationsthereof. The side panels 330 may have a thickness. The thickness of theside panel 330 may be about five (5) millimeters (mm). The thickness ofthe side panel 330 may be thicker or thinner than about five (5)millimeters (mm).

The bumpers 400 may be located underneath the receptacles 300 andsupported on a base 440. The base 440 may provide a generally planarplatform for the bumpers 400 and/or other parts of the system 100. Thebase 440 may be a structural support located at or near the bottom ofthe receiving system 250. The base 440 may be a metal frame or othersolid foundation, for example a metal platform on the ground in asorting and handling facility. The plurality of bumpers 400 may sit ontop of or otherwise be mounted to the base 440. In some embodiments, thebase 440 provides a structure to couple to the bumpers 400. The bumpers400 may be rigidly or fixedly attached to the base 440. In someembodiments, the bumpers 400 are supported on the base 440 in a fixedposition. Attachments well known in the art may be used, such as bolts,fasteners, screws, adhesive, tape, other suitable attachments, orcombinations thereof.

As shown, there may be four bumpers 400 (only partially shown) locatedunderneath the injector 200 (shown in FIGS. 1A and 1C-1E). In someembodiments, there may be more or fewer bumpers 400. The bumpers 400 maybe organized into clusters or groups alongside the track 360 with eachgroup underneath an injector 200. For instance, a first group of four(4) bumpers 400 may be located underneath a first injector 200 (forinstance, as shown in FIGS. 1A and 1C-1E), a second group (not shown) offour (4) bumpers 400 may be located underneath a second injector 200(not shown), and a third group (not shown) of four (4) bumpers 400 maybe located underneath a third injector 200 (not shown). The receptacles300 may travel to the first group of bumpers 400, and then to the secondand third groups along the track 360.

The bumpers 400 may have an elongated structure (the ends of which arepartially shown in FIGS. 1A-1B). The direction along which the bumpers400 are elongated may be aligned with the direction 15 of movement ofthe receptacles 300. The bumpers 400 may further extend through notchesin the receptacles 300 in a manner that is more fully described herein.The bumpers 400 may include an impact surface 410 (not shown in FIGS.1A-1D) that absorbs the impact of the item 10 within the receptacles 300as the receptacles 300 move over the bumpers 400. In some embodiments,the bumpers 400 are metal, plastic, polymer, other materials, orcombinations thereof. In some embodiments, the bumpers 400 are aluminum,steel, other metals, or combinations thereof. The bumpers 400 may besolid, hollow, or combinations thereof. Further details of the bumpers400 are discussed herein, for example with respect to FIGS. 2A-2C

The bumpers 400 may thus absorb an impact force of the item 10 byproviding a structure that occupies a lower part of the receiving space350 of the receptacle 300 (see FIGS. 1E-1G)). The impact force of theitem 10 is the reaction force of the structure with which the item 10primarily collides. That is, the impact force is the force that isprimarily responsible for bringing the item 10 to rest. Thus, while theitem 10 may impart a force on some part of the receptacle 300, such asthe front side 310, upon initially being received by the receptacle (seeFIG. 1E), it is understood that this is different from the term “impactforce” as used herein. Further, the impact force may be due to themomentum of the moving item 10. For example, the impact force may beapproximately proportional to the mass of the item 10 and the velocitywith which it is moving right before it collides with the bumper 400.The bumper 400 may act to intercept the item 10 as the item 10 moves andthus bear the brunt of the impact force. This may reduce, mitigate, orcompletely remove an impact force on the receptacle 300 from the item10. For instance, the bumper 400 may reduce or prevent the impact forcefrom the item 10 on the back side 340 of the receptacle 300 (see FIG.1E). The bumper 400 may also reduce or prevent the impact force from theitem 10 on other portions of the receptacle 300. The bumper 400 may alsoreduce or prevent the impact force from the item 10 on other parts ofthe system 100. Absorption of the impact force of the item 10 by theimpact surfaces 410 of the bumpers 400 is discussed in further detailherein, for example with respect to FIGS. 1E-1G and 4A-4D.

Turning to FIG. 1C, a partial front view of the system 100 is shown. Asshown, the front side 310 of the receptacle 300 is visible. A width andheight of the front side 310 is visible, where, as oriented, the widthin the lateral or horizontal direction is larger than the height in thevertical direction. The front side 310 may thus have a generallyrectangular planform or shape as viewed from the front. Otherconfigurations are possible, such as square, elongated, round, oval,others, or combinations thereof.

The receptacle 300 may include a gate 320. In some embodiments, thefront side 310 may be coupled with the gate 320 at or near the bottomportion 314 of the front side 310. By “coupled” it is meant that thecomponents are mechanically linked together, either directly linkedtogether, or indirectly linked to each other by intervening links, as isdiscussed in further detail herein, for example with respect to FIGS.1F-1G. The gate 320 may be a separate part from the front side 310. Thegate 320 may be an elongated and rigid structure along the width of thereceptacle 300 that prevents the items 10 from falling out of the bottomof the receptacle 300. The gate 320 may be formed of any suitablematerial. For example, the gate 320 may be made from a plastic, polymer,metal, other rigid material, or combinations thereof. The gate 320 mayhave a tapering thickness (see FIG. 1E). The thickness may taper fromabout half an inch (0.5″) to a quarter of an inch (0.25″). Thethicknesses may be thicker or thinner. The gate 320 may be rotatablycoupled at one end to the front side 310, as discussed in further detailherein, for example with respect to FIGS. 1E-1G.

The receptacle 300 may define a first notch 322. The first notch 322 maybe a space or cutout defined by edges and/or surfaces of the receptacle300 at or near a lower part of the receptacle 300. Thus the first notch322 may be defined by a structure or feature of the receptacle 300. Asshown, the first notch 322 is a cutout of the gate 320 of the receptacle300. In some embodiments, the first notch 322 is a cutout of the frontside 310. For example, in some embodiments without a gate 320, the firstnotch 322 may be at a lower part of the front side 310. In someembodiments, the first notch 322 is a cutout of a lower part of thefront side 310.

As shown, there may be multiple first notches 322 defined along thewidth of the gate 320. In some embodiments, the first notches 322 may bealong the width of the front side 310. As shown, there are four firstnotches 322. The first notch or notches 322 may be at least partiallydefined by segments 324 of the gate 320. The segments 324 are thoseparts of the receiving system 250, such as the gate 320 as shown, oneither side of the first notch or notches 322. In some embodiments,there are four first notches 322 in the receptacle partially defined byfive segments 324. As shown, the front side 310 is coupled with the gate320 which contains four first notches 322 and five segments 324. Thefirst notches 322 are shown with a generally rectangular shape. Othershapes are possible, such as square, rounded, curved, oval, elliptical,others, or combinations thereof. The segments 324 are shown with agenerally rectangular shape. Other shapes are possible, such as square,rounded, curved, oval, elliptical, others, or combinations thereof.Further, different segments 324 of the same receptacle 300 may havedifferent shapes and/or sizes. Thus, the segments 324 need not all havethe same geometry. As shown and as oriented in FIG. 1B, the segment 324near the middle of the width of the gate 320 has a different geometrythan the segment 324 on the right side of the gate 320.

Further shown in FIG. 1C are front views of the bumpers 400. As shown,the system 100 includes four bumpers 400. However, the system mayinclude more or fewer bumpers 400. The bumpers 400 may be spaced so asto absorb the impact force of the item 10 (not shown in FIG. 1C) nomatter where in the receptacle 300 the item 10 is received. Forinstance, as oriented in FIG. 1C, the left or right sides of thereceptacle 300 may initially receive the item 10 and one or more of thebumpers 400 in those respective locations may absorb the correspondingimpact force from the item 10. The bumpers 400 may be evenly spacedalong the width of the receptacle 300. The bumpers 400 may also bearranged or configured in other suitable configurations, such asunevenly spaced.

The multiple bumpers 400 may be aligned. As shown, the bumpers 400 arealigned and are generally parallel to one another. Thus, the bumpers 400may have an elongated shape (see FIGS. 2A-2C) where the bumpers 400 arealigned in a direction along the elongated dimension. In someembodiments, the bumpers 400 are aligned in the direction along whichthe receptacle 300 moves. For example, the receptacles 300 may be movingout of the plane of FIG. 1B such that the receptacles 300 move over thealigned bumpers 400.

As shown, the bumpers 400 may be aligned with the first notches 322. Forinstance, there may be four first notches 322 in the receptacle 300 withwhich the four bumpers 400 may be respectively aligned. Thus, a singlebumper 400 may be aligned with a single first notch 322. Otherconfigurations are possible. For instance, there may be multiple bumpers400 aligned with a single first notch 322, where the first notch 322 maybe wide enough to span the multiple bumpers 400. Some first notches 322may not be aligned with a bumper 400. For instance, the injector 200 maybe calibrated to propel items 10 only along a center portion of thereceptacle 300, in which the outer most bumpers 400 may not be present.

FIG. 1D depicts a partial rear view of the system 100. As shown, theback side 340 of the receptacle 300 is visible. A width and height ofthe back side 340 is visible. The back side 340 may have any or all ofthe features and/or functionalities as discussed herein with respect tothe front side 310. For instance, the back side 340 may have a generallyrectangular planform. As shown, the back side 340 extends along thewidth of the receptacle 300.

The receptacle 300 may define a second notch 344. The second notch 344may be a space or cutout defined by edges and/or surfaces of thereceptacle 300 at or near a lower part of the receptacle 300. The secondnotch 344 may have any or all of the features and/or functionalities asdiscussed herein with respect to the first notch 322. Thus the secondnotch 344 may be defined by the structure of the receptacle 300. In someembodiments, the second notch 344 is a cutout of the back side 340. Insome embodiments, the second notch 344 is a cutout at or near a bottomportion 342 of the back side 340. As shown, the bottom portion 342 is aportion of the back side 340 that is at or near the bottom of the backside 340. In some embodiments, the bottom portion 342 is a separate partthat is coupled with the back side 340. For instance, this may allow foreasy repair and or replacement of if the bottom portion 342 isdamaged—instead of having to repair or replace the entire back side 340,only the bottom portion 342 may need to be repaired or replaced.

The receptacle 300 may define multiple second notches 344 along thewidth of the back side 340. As shown, the receptacle 300 defines foursecond notches 344. The second notch or notches 344 may be at leastpartially defined by segments 346. The segments 346 are extensions ofthe receptacle 300 side that define the sides of the second notch ornotches 344. In some embodiments, there are five segments 346 thatdefine four second notches 344 in the receptacle 300. The segments 346may define second notches 344 that have a generally rectangular shape.Other shapes are possible, such as square, rounded, curved, oval,elliptical, others, or combinations thereof. The segments 346 are shownwith a generally rectangular shape. Other shapes are possible, such assquare, rounded, curved, oval, elliptical, others, or combinationsthereof. Further, different segments 346 of the same receptacle 300 mayhave different shapes and/or sizes.

The second notch or notches 344 defined by the receptacle 300 as shownin FIG. 1D may align with the first notch or notches 322 defined by thereceptacle 300 as shown in FIG. 1C. In some embodiments, the secondnotches 344 of the back side 340 may align with the first notches 322 ofthe front side 310. There may be four second notches 344 that each alignwith a respective first notch 322. In some embodiments, this alignmentis along the direction 15 (see FIGS. 1A-1B) of movement of thereceptacle 300. Thus, for example, the receptacle 300 may be moving intothe plane of the figure in FIG. 1C, which shows the first notches 322aligned with the second notches 344 in a direction that is perpendicularto this plane, i.e. in a direction that is parallel with the direction15 of movement of the receptacle 300. “Alignment” as used herein withrespect to the first and second notches 322, 344 does not necessarilymean that corresponding first and second notches 322, 344 are the samesize or shape. All that is required is that some portion of the firstnotch 322 overlaps with some portion of the corresponding second notch344 along an aligned direction. For instance, if the notches are alignedalong the direction 15 of movement of the receptacle 300, then alongthis direction at least some portion of the first notch 322 overlapswith at least some portion of the corresponding (aligned) second notch344.

The system 100 may include multiple bumpers 400 aligned with the firstnotch 322 and the second notch 344. Thus, each pair of first notches 322and second notches 344 that are aligned may also have one or more of thebumpers 400 aligned in between the two notches. Therefore, there may bemultiple sets of aligned notches 322, 344 with an aligned bumper 400 inbetween the aligned notches 322, 344. In some embodiments, the gate 320of the front side 310 comprises a plurality of first notches 322corresponding to the plurality of bumpers 400, i.e. there may be thesame quantity of bumpers 400 as the quantity of first notches 322, andthe plurality of first notches 322 may be aligned with the plurality ofsecond notches 344, with each bumper 400 occupying a respective portionof the interior of the receptacles 300 between corresponding alignedfirst and second notches 322, 344. In this manner, each bumper 400 maybe at least partially exposed in a portion of the interior of thereceptacles 300 between the first and second plurality of notches 322,344. As shown in FIGS. 1C-1D, there are four sets of bumpers andnotches, where each set has the first notch 322, the second notch 344and the bumper 400 all aligned with respect to each other.

Referring to FIG. 1E, a section view of the system 100 is shown as takenalong line 1E-1E as indicated in FIG. 1C. FIG. 1E shows the receptacles300 in section view so that the interiors of the receptacles 300 arevisible. Therefore, FIG. 1E depicts cross sections of the front sides310 and back sides 340 of the receptacles 300.

Each front side 310 of the receptacles 300 may be generally flat with athickness. The thickness may be substantially uniform along a height ofthe front side 310. The front side 310 may include a top portion 312near the top of the interior of the front side 310. The top portion 312refers to an area of the front side 310 that is generally on the upper,interior surface of the front side 310. The front side 310 may alsoinclude a bottom portion 314 near the bottom of the interior of thefront side 310. The bottom portion 314 refers to an area of the frontside 310 that is generally on the lower, interior surface of the frontside 310.

Cross sections of the back sides 340 of the receptacles 300 are shown inFIG. 1E. The back side 340 may have a contour that includes asubstantially vertical lower portion 342 and an angled upper portion341. The thickness of the back side 340 may be substantially uniformalong this contour of the back side 340.

As shown, the receptacles 300 may share a common structural member. Thatis, the back side 340 of a receptacle 300 may be formed from the same,continuous structure as the front side 310 of an adjacent receptacle300. As oriented in FIG. 1E, the first and second receptacles 300 fromthe right share a structural member as do the second and thirdreceptacles 300. For instance, as oriented in FIG. 1E the back side 340of the first receptacle 300 on the right shares a structural member withthe front side 310 of the receptacle 300 that is second from the right.Similarly, as oriented in FIG. 1E, the back side 340 of the secondreceptacle from the right shares a common structural member with thefront side 310 of the receptacle 300 that is third from the right.However, the back side 340 of the third receptacle 100 from the rightdoes not share a structure with another receptacle to the left. This isbecause the receptacles 300 are grouped together in groups of three, asmentioned. In some embodiments, the receptacles 300 may be in groupswith more or fewer receptacles 300. This configuration of sharing acommon structural member allows for a more efficient use of materialsand assembly time. In some embodiments, the receptacles 300 may each beformed from separate structures.

As shown, the gate 320 may have a guiding surface 316. The guidingsurface 316 may be a surface of the gate 320 that faces the interior ofthe receptacle 300. The guiding surface 316 may redirect, steer orotherwise guide the injected item 10 as the item 10 moves over theguiding surface 316. The guiding surface 316 may guide the item 10 fromthe front side 310 and toward and/or into a final direction of travel30, as discussed in further detail below.

As shown, the guiding surface 316 forms a curvature as viewedtransversely. In some embodiments, the guiding surface 316 forms acurvature that is rounded. The surface 316 is shown as generally roundedor circular. However, other shapes or contours are possible. The surface316 may form a curvature that is a radial curve, such as with a circle,or it may form other curves, such as elliptical, oval, other roundedcontours, and/or combinations thereof. The surface 316 may also includestraight or flat segments. In some embodiments, the surface 316 may forma curvature that is curved, straight, segmented, other shapes, and/orcombinations thereof. Further, the surface 316 may form a curvature thatcomprises flat segments. For example, the surface 316 may be comprisedof multiple, short flat segments. In some embodiments, the surface 316may be a combination of rounded and flat segments. In some embodiments,the surface 316 may be entirely or mostly straight.

An impact surface 410 of the bumper 400 is further shown in FIG. 1E. Theimpact surface 410 may be a surface or other feature of the bumper 400that absorbs the impact force of the item 10. In this context, by“absorb” it is meant that the impact force is imparted to the impactsurface 410 from the moving item 10 and that the impact surface 410 isprimarily responsible for bringing the item to rest within thereceptacle 300. Further details of the “impact force” are describedherein, for example with respect to FIGS. 1A-1B. In some embodiments,the impact surface 410 extends at least partially into the receivingspace 350 of the receptacle 300. In some embodiments, the impact surface410 is configured to absorb the impact force of the item 10 inside thereceiving space 350. In some embodiments, the impact surface 410 ispositioned such that it intersects the final direction of travel 30 ofthe item 10. Thus, the impact surface 410 may absorb most or all of theimpact force from the moving item 10.

Each receptacle 300 may define a receiving space 350 on the interior ofthe receptacle 300. The receiving space 350 refers to the pocket orcavity inside the receptacle 300 that receives the item 10. Thereceiving space 350 is thus defined or formed by the structure aroundits perimeter or boundary. As shown in FIG. 1E, the front side 310 maydefine a portion of this boundary of the receiving space 350. Thisportion of the boundary of the receiving space 350 extends from the topportion 312 of the front side 310 to the bottom portion 314 of the frontside 310. This part of the receiving space 350 may thus be generallyflat.

Continuing along the interior of the receptacle in a clockwisedirection, another part of the boundary of the receiving space 350 maybe defined by the gate 320. Thus the guiding surface 316 of the gate320, which faces the interior of the receptacle 300, may define anotherpart of the boundary of the receiving space 350. This part of thereceiving space 350 may thus be curved, due to the curvature of theguiding surface 316 of the gate 320.

Continuing in a clockwise direction, another part of the boundary of thereceiving space 350 may be defined by the interior of the back side 340.This portion of the boundary of the receiving space extends from a lowerarea of the interior of the back side 340 to an upper area of theinterior of the back side 340. This part of the receiving space 350 maythus be angled.

Continuing in a clockwise direction, another part of the boundary of thereceiving space 350 may be defined by the uppermost edges of the backside 340 and front side 310. As mentioned, the receptacles 300 are openat the top so that the item 10 may be received by the receptacle throughthe top. Thus, the upper boundary of the receiving space 350 is definedby a plane that contacts both the top portions of the front and backsides. It is understood that this plane is merely a geometric constructfor explanation and clarity, and that it is not a physical part of thesystem 100.

The receiving space 350 further includes the interior space within theboundary just described. The receiving space 350 may include the spacewhere the item 10 is initially received within the receptacle 300, suchas near the top of the receptacle 300 as illustrated. The receivingspace 350 may include any other space where the item 10 travels withinthe receptacle 300, such as near the bottom of the receptacle 300 asillustrated. The receiving space 350 may be defined at least in part bythe space that is in between the front side 310 and the back side 340.As illustrated, this is the upper area of the receptacle 300 between thefront side 310 and the back side 340. The receiving space 350 may alsoinclude the area where the item 10 comes to rest within the receptacle300. As illustrated, this is the lower area of the receptacle 300between the front side 310 and the back side 340. The receiving space350 may also include any areas within the receptacle 300 in betweenthese upper and lower areas.

The receptacle 300 may be positioned so as to receive the item 10 in thereceiving space 350. For example, as mentioned the receptacles 300 maybe moved along the track 360 by the motor and chain (not shown). In someembodiments, the timing of the movement of the receptacles iscoordinated with the timing of the injection of the items 10 from theinjector 200 such that the bumpers 400 extend into the receiving space350 when the item is received in the receiving space 350.

Other scenarios with relative motion are possible as well. For instance,both the bumper 400 and receptacle 300 may be moving but at differentvelocities or speeds such that there is relative motion between thebumper 400 and receptacle 300. In some embodiments, the receptacle 300translates relatively quickly from left to right as illustrated whilethe bumper 400 may move relatively more slowly. In some embodiments, thereceptacle 300 translates from left to right as illustrated while thebumper 400 may move slightly to absorb the impact force of the item 10.For example, the bumper 400 may be mounted on elastic shock absorbers,such as springs (not shown), to further attenuate the impact force ofthe item 10. Thus, the receptacle 300 may translate while the bumper 400rebounds slightly from the impact force. Further, the receptacle 300and/or bumper 400 may move in more than one dimension. For example, thebumper 400 may be mounted on springs in such a manner to allow forvibratory motion in two dimensions, such as horizontally and vertically.

Positioning the receptacle 300 so as to receive the item 10 in thereceiving space 350 may include positioning the receptacle 300 such thatthe receiving space 250 is intersected by an initial direction of travel20 of the item 10. The initial direction of travel 20 of the item 10 maybe the initial direction that the item 10 is travelling or otherwisemoving. The initial direction of travel 20 may be a linear direction,such as a line. It may also be curved, linear, other shapes, orcombinations thereof. In some embodiments, the injector 200 may propelthe item 10 along the initial direction of travel 20. For example, theinjector may emit the item 10 such that the item 10 is propelled throughthe air along a generally linear and/or slightly curved initialdirection of travel 20.

The initial direction of travel 20 may be angled with respect to thefront side 310 of the receptacle 300. As shown, the initial direction oftravel 20 is slightly angled with respect to the front side 310. In someembodiments, the front side 310 is generally vertical while the initialdirection of travel 20 is less than forty five degrees (45°) off thevertical. Other angles may be used, and this is merely one example.

The item 10 may travel along the initial direction of travel 20 andcontact the receptacle 300 at the top portion 312 of the front side 310.The item 10 may initially contact the top portion 312 when received bythe receptacle 300. In some embodiments, the item 10 may initiallycontact other portions or areas of the receptacle 300.

The item 10 may also contact a bottom portion 314 of the receptacle 300.The item 10 may initially contact the top portion 312 and then slidedown or otherwise travel or move to the bottom portion 314.

The item 10 may then be guided along or otherwise by the guiding surface316 toward and/or into a final direction of travel 30. In someembodiments, the guiding surface 316 may guide the item 10 from thefront side 310 and toward and/or into the final direction of travel 30.The final direction of travel 30 is the direction of travel of the item10 upon impact with the bumper 400 inside the receiving space 350. It istherefore understood that the final direction of travel 30 as usedherein may not necessarily refer to the last or final direction alongwhich the item 10 may move. For instance, the item 10 may impact thebumper 400 and rebound in another direction. The final direction oftravel 30 may be a linear direction such as a line, a curved direction,other direction, or combinations thereof. The final direction of travel30 may further be in a different direction than the initial direction oftravel 20. As shown, there are roughly 80 degrees (80°) between thefinal direction of travel 30 and the initial direction of travel 20. Insome embodiments, there may be sixty degrees (60°), seventy degrees(70°), ninety degrees (90°) or other angular amounts between the finaldirection of travel 30 and the initial direction of travel 20. These aremerely examples, and the final direction of travel 30 may be at manyother angles with respect to the initial direction of travel 20.

In some embodiments, as the item 10 is travelling along the finaldirection of travel 30, the item 10 is intercepted by the impact surface410 of the bumper 400 which absorbs the impact force of the moving item10. The system 100 may thus include the impact surface 410 of the bumper400 extending into the receiving space 350 between the notches. Thus,the impact surface 410 may occupy the receiving space between the firstnotch 322 and the second notch 344 of the receptacles 300. The impactsurface 410 may be positioned so as to absorb the impact force of theitem 10. The impact surface 410 may be positioned so as to absorb theimpact force of the item 10 after the item 10 is guided by the guidingsurface 316 into the final direction of travel 30.

In some embodiments, there is relative movement between the receptacle300 and the bumper 400 and the item 10 impacts the impact surface 410when the impact surface 410 is aligned with and in between the first andsecond notches 322, 344 (shown in FIGS. 1C-1D). In some embodiments, thereceptacles 300 are moving and the item 10 impacts the impact surface410 when the impact surface 410 is between the first and second notches322, 344. In some embodiments, the receptacles 300 are moving, thebumpers 400 are stationary and the item 10 impacts the impact surface410 when the impact surface 410 is between the first and second notches322, 344. In some embodiments, the receptacles 300 are moving and theinjector 200 propels the item 10 into the receptacle 300 such that theitem 10 impacts the impact surface 410 when the impact surface 410 isbetween the first and second notches 322, 344. Therefore, the movementof the item 10 and/or the receptacle 300 may be timed or otherwisecoordinated so that the item 10 impacts the impact surface 410.

FIG. 1F depicts a detail view of a lower portion of the receiving system250. The detail view of FIG. 1F is taken from the section view of FIG.1E as indicated by the dashed detail box in FIG. 1E. As shown in FIG.1F, the impact surface 410 of the bumper 400 is in the receiving space350 in between the gate 320 and the back side 340. As mentioned, thegate 320 may merely be a lower part of the front side 310. The gate 320may therefore be the bottom portion 314 of the front side 310.

As depicted, the gate 320 is coupled with the bottom portion 314 of thefront side 310. By “coupled” it is meant that the components aremechanically linked together, either directly linked to each other, orindirectly linked to each other by intervening links. As shown, the gate320 is coupled with the front side 310 by a pin 321. The pin 321 may bean elongated rod that couples with the gate 320 and the front side 310.In some embodiments, the gate 320 is coupled with the front side 310 byother mechanical means, such as bolts, shear pins, hinges, or otherstructural members. These are merely examples and other suitablefeatures may be used.

In some embodiments, the gate 320 may be pivotably or rotatably coupledto the front side 310. In some embodiments, the gate 320 may bepivotably coupled to the front side 310 by the pin 321. The pivotablecoupling allows the gate 320 to pivot or otherwise rotate. In someembodiments, the gate 320 may be pivotably coupled to the front side 310by the pin 321 and thereby be pivotable about the pin 321. The gate 320may pivot to a closed position. In the closed position, the gate 320 mayprevent the item 10 from exiting the receptacle 300 near the bottomportion 342 of the back side 340. The gate 320 is shown in a closedposition in FIGS. 1F and 1G. The gate 320 may also pivot to one or moreopen positions. In the open position, the gate 320 may not prevent theitem 10 from exiting the receptacle 300 near the bottom portion 342 ofthe back side 340. In some embodiments, the gate 320 may pivotcounterclockwise, as oriented in FIGS. 1F and 1G, to the open position.

The gate 320 may be in a closed position while the receptacle isreceiving the item 10. After the receptacle has received the item 10,then the gate 320 may be opened at an unloading site to allow the item10 to exit the receptacle. For example, the receptacle 300 may receivethe item 10 from the injector 200, and the item 10 may be guided by thefront side 310 and the guiding surface 316 of the gate 320 to impact theimpact surface 410. The gate 320 may then contain the item 10 inside thereceptacle 300 such that the item 10 does not fall out of or otherwiseexit the receptacle 300. The receptacle 300 may then move to anotherlocation of the facility, such as the unloading site, where the item 10is to be dropped into a bin for further sorting, delivery, etc. At thispoint, the gate 320 may move to an open position to allow the item 10 todrop or otherwise exit the receptacle 300. In some embodiments, the gate320 may rotate or otherwise pivot to this open position.

FIG. 1G depicts the detail view of FIG. 1F with the addition of areceived item 10. The item 10 may be a piece of mail. In someembodiments, the item 10 is a piece of flat mail, a package, a magazineor any other item that may be handled, sorted, and/or received.

The item 10 is shown impacting the impact surface 410 of the bumper 400.In some embodiments, the bumper 400 is separate from the receptacle 300,thus separating the functions of absorbing the impact force andreceiving the item 10. In other words, the bumper 400 may absorb theimpact force while the receptacle 300 receives and then transports theitem 10. In this manner, the receptacle 300 is not subject to repeatedloadings from a high volume of items 10 being received by the receptacle300. This division of labor has a cascading effect in terms of improvedefficiency and less required time and cost of the system 100. Forinstance, the receptacle 300 thus need not be structurally reinforcedbecause it is not bearing the brunt of the impact force. This allows thereceptacle 300 to be lighter, saving material and manufacturing costs,and thus requiring less power to move the lighter receptacle 300,further saving costs. Further, the receptacles 300 will be damaged lessoften and will last longer, which reduces the frequency of downtimewhere a receptacle 300 must be removed from the system 100 for repairingor replacing. These are just some of the advantages of the system 100.

The item 10 may impact a single impact surface 410 on a single bumper400. For example, a smaller item 10 may only impact a single impactsurface 410. In some embodiments, an item 10 may impact multiple impactsurfaces 410 on multiple bumpers 400. For example, a larger item 10 suchas an elongated piece of mail may impact multiple impact surfaces 410.

FIGS. 2A-2C depict various views of various embodiments of the bumper400. As shown in FIG. 2A, a side view of an embodiment of a bumper 400that may be used with the system 100 is depicted. As shown, the bumper400 may include a member 405. The member 405 may be the main materialfrom which some, most of, or the entire bumper 400 is made. In someembodiments, the member 405 is plastic, metal, other materials, orcombinations thereof. In some embodiments, the member 405 is aluminum,steel, other metals, or combinations thereof. The member 405 may besolid, hollow, or combinations thereof.

The bumper 400 may include a top 445. The top 445 refers to the side orsides of the bumper 400 that generally face the receptacle 300 whenconfigured in the system 100. The top 445 may include a front portion450. As shown, the front portion 450 may be sloped or angled. The frontportion 450 may be angled to ensure that receptacles 300 that alreadyhave items 10 inside them before they reach the bumpers 400 can passsmoothly over the bumpers 400. For example, in some embodiments, thesystem 100 has multiple injectors 200 with multiple sets of bumpers 400.Thus, a first injector 200 may inject an item 10 into the receptacle300, which may then travel over another set of bumpers 400 locatedfurther down the track 360. The angled front portion 450 of the bumper400 located further down the track 360 facilitates a smooth movement ofthe item 10 inside the receptacle 300 over the bumper 400. The top 445may include a back portion 460. As shown, the back portion 460 may beflat. The top 445 may include the impact surface 410. As shown, theimpact surface 410 may be in between the front and back portions 450,460. The impact surface 410 may also be on a front end (i.e. on theleft, as oriented in FIG. 2A) of the back portion 460. The impactsurface 410 may be a generally vertical surface. In some embodiments,the impact surface 410 may be angled. For instance, the impact surface410 may be angled so as to be perpendicular to a non-horizontal finaldirection of travel 30 of the item 10. Other suitable configurations andorientations of the impact surface 410 are possible and are discussedherein, for example with respect to FIGS. 3A-3C.

The bumper 400 may include a layer 482. The layer 482 may be on portionsof the bumper 400. The layer 482 may cover the entire top 445 of thebumper 400 or portions thereof. As shown, the layer 482 covers the frontend 478, the front portion 450, the impact surface 410 and the backportion 460. The layer 482 may have a thickness. The bumper 400 shownhas a relatively thin layer 482 with respect to the overall height ofthe bumper 400, but other thicknesses may be implemented. In someembodiments, the layer 482 is made from sheet metal. The layer 482 maybe stainless steel sheet metal. In some embodiments, the member 405 ismade from aluminum and the layer is made from stainless steel sheetmetal. The layer 482 may be a protective layer. The layer 482 may helpwith absorbing the impact of the item 10. The layer 482 may cover theimpact surface 410. In some embodiments, the layer 482 supplements theimpact surface 410 by providing an extra layer with which to absorb theimpact force of the item 10. In some embodiments, the layer 482 providesthe impact surface 410.

The bumper 400 may also include a bottom 470. The bottom 470 may includea cutout 474. The bumper 400 may also include a side 472. The side 472may couple the top 445 to the bottom 470. In some embodiments, thebumper 400 has two sides 472, which are opposite each other. (Both sides472 are shown in FIG. 2B.) As further shown in FIG. 2A, the bumper 400may have a front end 478. The front end 478 may couple the top 445 tothe bottom 470. The bumper 400 may have a back end 480. The back end 480may couple the top 445 to the bottom 470.

FIG. 2B depicts a top view of the bumper 400 of FIG. 2A. As shown inFIG. 2B, the bumper 400 has a generally rectangular planform. However,the bumper may have other suitable shapes, such as triangular,trapezoidal, others, or combinations thereof. The two sides 472 areshown as opposite each other.

FIG. 2C depicts a section view of the bumper 400 as taken along line2C-2C as shown in FIG. 2B. As shown in FIG. 2C, the bottom 474 mayinclude holes 476. The holes 476 may be along the bottom 470. The holes476 may be used to attach the bumper 400 to the base 440 (see FIGS.1A-1C). The holes 476 may be bolt holes or other fastening features tocouple the bumper 400 to the base 440. The holes 476 may be along thetop 445. The holes 476 may be used to attach the layer 482 to the bumper400. As depicted in FIG. 2C, the holes 476 along the top 445 are shownwith fasteners that are attaching the layer 482, while the holes 476along the bottom 470 are not shown with fasteners.

FIGS. 3A-3B depict side views of schematics of a portion of variousembodiments of the bumper 400 that may be used with the system of FIG.1A. The portions of the bumper 400 shown in FIGS. 3A-3B depict variousembodiments of the impact surface 410 and adjacent portions of the top445. For clarity, the bumpers 400 are shown without the layer 482.

As shown in FIG. 3A, the impact surface 410 may be a projection. Theimpact surface 410 may project from the top 445 of the bumper 400. Asshown, the impact surface 410 is triangular in shape and extends upwardfrom other surfaces of the top 445. In some embodiments, there may onlybe a single projection impact surface 410. In other embodiments, asshown, there may be multiple projection impact surfaces 410. Havingmultiple impact surfaces may facilitate the item 10 (not shown)impacting the impact surface 410 when the receptacle 300 (not shown) isin the right position. For instance, if the item 10 does not impact theright-most impact surface 410 as illustrated, then the item 10 mayimpact the left-most impact surface 410, or vice versa. By having atriangular shape of the impact surface 410, multiple such projectiontype impact surfaces 410 may be implemented close together, furtherincreasing the likelihood of successful impact with the item 10 andloosening timing requirements of the system 100. The projection typeimpact surface 410 may be triangular or any other suitable shape, suchas rectangular, square, pentagonal, other shapes, or combinationsthereof. In some embodiments, more than two projection type impactsurfaces 410 may be implemented, such as three, four or more.

As shown in FIG. 3B, the impact surface 410 may be a recess. The impactsurface 410 may extend into the top 445 of the bumper 400. As shown, theimpact surface 410 is triangular in shape and extends inward from thetop 445. In some embodiments, there may only be a single recess impactsurface 410. In other embodiments, as shown, there may be multiplerecess impact surfaces 410. Having multiple impact surfaces mayfacilitate the item 10 (not shown) impacting the impact surface 410 whenthe receptacle 300 (not shown) is in the right position, as mentionedabove with respect to FIG. 3A. The recess impact surface 410 may betriangular or any other suitable shape, such as rectangular, square,pentagonal, other shapes, or combinations thereof. In some embodiments,more than two recess type impact surfaces 410 may be implemented, suchas three, four or more.

As shown in FIG. 3C, the impact surface 410 may be a flat step. Thisconfiguration may be similar to that shown in FIGS. 2A-2C, with theexception that the front portion 450 is flat. Other configurations ofthe bumper 400 with a flat step impact surface 410 may be implemented,and this is merely one example.

FIGS. 4A-4D depict side views at sequential points in time of anembodiment of a receptacle 300 receiving an item 10. Chronologically,the figures are in order of earliest to latest in time from FIG. 4A toFIG. 4D. As shown, the injector 200 and bumper 400 are stationary. Whileonly one bumper 400 is shown, there may be multiple bumpers 400. Forinstance, other bumpers 400 may be behind the bumper 400 that isvisible. Further, while only one receptacle 300 in the group of threereceptacles 300 is shown receiving an item 10, this is merely forclarity. In some embodiments, adjacent receptacles 300 may all receivedifferent items 10. There may also be more or fewer receptacles, forexample nine (9) receptacles 300 as shown and discussed with respect ofFIGS. 1A-1B. In some embodiments, there are two hundred and fifty three(253) receptacles 300.

As shown in FIG. 4A, the injector 200 contains the item 10. The injector200 is beginning to propel the item 10. In some embodiments, the item 10is beginning to move along the initial direction of travel 20. The item10 may thus be propelled by the injector 200 along the initial directionof travel 20. Further, the receptacle 300 is shown moving from left toright as illustrated relative to the stationary injector 200 and bumper400. Thus, the initial direction of travel 20 is shown initiallyintersecting the right-most receptacle as illustrated.

As shown in FIG. 4B, the injector 200 is emitting and propelling theitem 10. The item 10 is travelling along the initial direction of travel20. In some embodiments, the item 10 is propelled at a speed ofapproximately 3.4 meters per second (m/s). Further, the receptacle 300has moved to the right relative to the position shown in FIG. 4A. Insome embodiments, the receptacle 300 moves at a speed of approximately0.6 m/s. Thus, the initial direction of travel 20 is now intersecting atop portion 312 of the front side 310 of the middle receptacle 300 asillustrated. The item 10 may thus travel toward the top portion 312 ofthis front side 310. Further, the initial direction of travel 20 may beat a slight angle with the front side 310. This results in a small forcewith the front side 310, as most of the force component is parallel tothe front side 310. Thus a shear or sliding force, such as a frictionforce, may be imparted along the surface of the front side 310 asopposed to a normal force on the front side 310. This arrangementresults in less damage to the receptacle 300 because the shear stressesor friction forces imparted to the front side 310 are less damaging thana normal force, the latter of which may tend to bend the front side 310.The sliding of the item 10 along the front side 310 also positions theitem 10 to be guided by the guiding surface 316 of the receptacle 300.

As shown in FIG. 4C, the item has contacted the middle receptacle 300.The receptacle 300 has now moved to the right relative to the positionshown in FIG. 4B. The item 10 is now beginning to slide down the frontside 310. Thus, the item initially contacts the front side 310. The item310 may also initially contact the top portion 312, the bottom portion314, or other portions therebetween of the front side 310. For example,as shown, the item 10 is initially contacting the front side 310 atabout the middle of the front side 310. The item 10 may bend uponcontacting the front side 310. For example a flexible piece of mail maycontact the front side 310 and bend in order to slide down the frontside 310. The item 10 is shown bent and sliding toward the bottomportion 314 of the front side 310.

As shown in FIG. 4D, the receptacle 300 has moved to the right relativeto the position shown in FIG. 4C. The item 10 is sliding over theguiding surface 316 of the bottom portion 314, which is guiding the item10 to a final direction of travel 30. The item 10 is also impacting theimpact surface 410 which is intersected by the final direction of travel30. The item 10 is thus impacting the bumper 400, which is absorbing theimpact force from the item 10.

As mentioned, the de-coupling of the bumper 400 and receptacle 300structurally and functionally creates many advantages. With FIGS. 4A-4D,the relative motion of the various components of the system 100 in anembodiment is apparent. The receptacle 300 is moving toward the right asillustrated. The item 10 is received by the receptacle 300 and is guidedor re-directed by the guiding surface 316 of the bottom portion 314generally to the left as illustrated. Thus, in some embodiments, theitem 10 eventually is moving in the opposite direction as the receptacle300. Therefore, if the item 10 were to impact the receptacle 300 asopposed to the impact surface 410, the force would be additive. That is,the speed of the receptacle 300 travelling to the right and the finalspeed of the item 10 travelling to the left would result in a largereffective impact force, due to the opposing directions of travel. Forexample, if the receptacle 300 is moving to the right at about 3.4 m/sand the item 10 is moving at about 0.6 m/s to the left along ahorizontal final direction of travel 30, then the total effective speedof the item 10 at impact would be about 4.0 m/s.

In contrast, with the stationary bumper 400, this additive effect on thespeed is negated. Because the bumper 400 is stationary, there is noother component of force added, as would be the case if the item 10impacted the moving receptacle. For example, if the item 10 is propelledat 3.4 m/s, then the effective speed of the item 10 is now merely thepropelled speed of the item 10, or 3.4 m/s. Thus, not only is the impactforce removed from the receptacle 300, but the amount of the impactforce on the impact surface 410 is reduced. This further results in lessforce imparted to the bumper 400, resulting in longer-lasting bumpers400. It also results in less force on the item 10, resulting in fewerdamaged items 10. And, as mentioned, the receptacles 300 are subject toless force, if any at all, from the final impact of the item 10. All ofthese advantages and others result in a more robust system 100 thatrequires less maintenance, less repair, and less downtime, thus savingtime and money over the life of the system 100 and facilitating moreprofitable operations.
